In looking at the used kegs where I lived in NYC, most were not much cheaper, maybe $30 than the new ones I could get on MoreBeer, so thought about going new on those. But slowly I want to get pieces together. Plus I may return to CA this year, so if I do this, I may just buy pieces slowly, store with my parents and build a kegerator there I will have more space. Thats why I thought, start with the regulator right now. By a couple of new kegs in a few months, and then tubing, C02 at the end.
